Engine ping, driving me crazy......
I've got a hd 95inch stage 2 and the ping on hot days, with the wife on the back, is really getting to me.I have tried efi carbon cleaner, se colder big bore plugs, got into the sert, dropped low speed af by 1.5, tried richening the accel mode, no help, dropped timing by 2.5, no help, sprayed either around throttle bodies for possible air leak, no help, anyone have anymore thoughts, or do I get some ear plugs?

Where would I find sea foam?, never heard of it, though I'm not much for octane booster and such, I will try a can. Funny thing with the dyno guys, I've asked a few questions on the sert and what area to work on, and there lips are always sealed. I know I cant ride a dyno, and I'll never race one, if the bike didn't ping I would be happy, it pulls well and gets good mileage still(44-48).

There are different fixes for different problems, of course. My 95" pinged until I took it on a high speed/RPM ride on a hot day. I rode from Las Vegas to L.A. and back the next day. I rode as hard as I dared, as hot/high RPM as I dared. It blew the carbon off and out of the motor. It didn't ping for several hundred miles of city driving. When it starts again I go for a hard ride for a dozen or so miles. It's fun and a good excuse to ride hard. Good Luck

I bet that pinging is detonation which is not good. Mine did it nearly every shift after a 103 stage 2 when the weather turned hot and I opened the throttle even though the dealer who did the work did a new dyno. Took it to another dealer, where I should have gone first, a new custom map with my SERT and the ping is gone. You may want to consider an expert dyno operator. Good luck!
